Answer:
DEFINITION
Noise pollution is generally defined as regular exposure to elevated sound levels that may lead to adverse effects in humans or other living organisms. According to the World Health Organization, sound levels less than 70 dB are not damaging to living organisms, regardless of how long or consistent the exposure is. Exposure for more than 8 hours to constant noise beyond 85 dB may be hazardous. If you work for 8 hours daily in close proximity to a busy road or highway, you are very likely exposed to traffic noise pollution around 85dB.
This type of pollution is so omnipresent in today’s society that we often fail to even notice it anymore:
street traffic sounds from cars, buses, pedestrians, ambulances etc.
construction sounds like drilling or other heavy machinery in operation
airports, with constant elevated sounds from air traffic, i.e. planes taking off or landing
workplace sounds, often common in open-space offices
constant loud music in or near commercial venues
industrial sounds like fans, generators, compressor, mills
train stations traffic
household sounds, from the television set to music playing on the stereo or computer, vacuum cleaners, fans and coolers, washing machines, dishwashers, lawnmowers etc.
events involving fireworks, firecrackers, loudspeakers etc.
conflicts generate noise pollution through explosions, gunfire etc. The dysfunctions, in this case, are likely caused by the conflict and insecurity and less by the noise pollution in itself, although that compounds stress levels too.
Human Diseases Caused by Noise Pollution
Whether we realize we are subjected to it or not, noise pollution can be hazardous to our health in various ways.
Hypertension is, in this case, a direct result of noise pollution caused elevated blood levels for a longer period of time.
Hearing loss can be directly caused by noise pollution, whether listening to loud music in your headphones or being exposed to loud drilling noises at work, heavy air or land traffic, or separate incidents in which noise levels reach dangerous intervals, such as around140 dB for adult or 120 dB for children.
Sleep disturbances are usually caused by constant air or land traffic at night, and they are a serious condition in that they can affect everyday performance and lead to serious diseases.
Child development. Children appear to be more sensitive to noise pollution, and a number of noise-pollution-related diseases and dysfunctions are known to affect children, from hearing impairment to psychological and physical effects. Also, children who regularly use music players at high volumes are at risk of developing hearing dysfunctions. In 2001, it was estimated that 12.5% of American children between the ages of 6 to 19 years had impaired hearing in one or both ears
Various cardiovascular dysfunctions. Elevated blood pressure caused by noise pollution, especially during the night, can lead to various cardiovascular diseases.
Dementia isn’t necessarily caused by noise pollution, but its onset can be favored or compounded by noise pollution.
Psychological dysfunctions and noise annoyance. Noise annoyance is, in fact, a recognized name for an emotional reaction that can have an immediate impact.
Answer:
In other words, high volume noises are abnormal. As the world is advancing at a rapid rate, so is noise pollution. Technology has made things easier for people by creating appliances and devices for almost everything. You want to mix or grind something? It can be done with a mixer and blender. You are feeling hot? Simply turn on the AC or cooler. Do you want entertainment at home? You can watch television or play music. However, people don’t realize this comfort comes with harmful effects too. All the mentioned appliances contribute to noise pollution. They disturb the natural rhythm of life and fall in the category of a pollutant.
What causes Noise Pollution?
As the world is turning to technology for their comfort, it is, at the same time, harming us. The industries no matter how big or small contribution to noise pollution. The equipment they use like compressors, exhaust fans, generators and more produce a lot of noise.
Similarly, the ever-increasing use of automobiles is a major cause of this pollution. Not only automobiles but other transport vehicles like airplanes, buses, bikes, trucks and more also are a part of it. People honk unnecessarily in the traffic and listen to loud music on the way which creates high levels of noise.
Furthermore, social events like marriages, parties, and religious functions in places like clubs, pubs, temples, halls and more create a lot of nuisance in the residential areas. In addition, the construction activities like mining, the building of flyovers, bridges and more also produce great noise.
The Damaging Impact of Noise Pollution
Though it may not be talked about much, noise pollution has a serious impact on the lives of living beings. Firstly, noise pollution causes a number of hearing problems. High levels of noise damage the Eardrums and sometimes even cause loss of hearing.Similarly, it reduces the ear sensitivity to the sounds that the human body requires to regulate our rhythm of the body. Moreover, it also affects our psychological health. It may not be evident instantly, but in the long run, it changes our behavior.
When your sleep gets disturbed or you constantly have headaches because of too much noise, you tend to experience fatigue and even migraines.
Not only humans but noise pollution also impacts wildlife too. For instance, pets become aggressive or afraid when they hear a loud noise. It is one of the main reasons why crackers are not encouraged when pets are around.
In short, we must make people aware of the impact of noise pollution. Likewise, we must encourage them to adopt ways that do not contribute to noise pollution. If everyone starts doing the same on an individual level, we will surely be able to reduce noise pollution to a great extent.
